My direct experience is, however, that L uplink on AO-40 was far better using a 1.2m dish than using two 22 element Yagi antennas on that band, either collinear or CP. This is as published in QST.

I agree that a 2-foot dish is useless at 1.26 GHz as it's slightly more than 2-wavelengths in diameter. S-band barely works at 4.5-wavelengths.
A C/X transponder seems feasible as there are efficient 500 mW X-band amplifier MMICs available. See the attached document.
